The device for cooling fresh air, comprising a water injector (2), a water tank (3), a water pump (4) and a casing (5), the water tank (3) via the water pump (4) with the water injector (2) connects, and a pressure accumulator (6) for storing water (7), wherein the pressure accumulator (6) between the water pump (4) and water injector (2) is arranged.
Description
Die Erfindung betrifft eine Vorrichtung zum Einspritzen von Wasser zum Kühlen von sich in einem Verbrennungsraum befindenden oder dieser zugeleiteten Frischluft und der im weiteren Verlauf sich ergebenen Verbrennungsgastemperaturen. The invention relates to a device for injecting water for cooling in or passing a fresh air supplied in a combustion chamber and the resulting in the course of combustion gas temperatures.
Es ist bekannt, eine Wassermenge gezielt in einen Verbrennungsraum eines Verbrennungsmotors einzuführen, um ein Klopfen, d.h., eine unkontrollierte Zündung eines sich im Verbrennungsraum befindlichen Kraftstoff-Luft-Gemisches, zu unterdrücken. Ein solches Verfahren offenbart beispielsweise die
Die erfindungsgemäße Vorrichtung zum Einspritzen von Wasser zum Kühlen von sich in einem Verbrennungsraum befindenden oder dieser zugeleiteten Ladeluft umfasst einen Wasserinjektor, einen Wassertank, eine Wasserpumpe und eine Verrohrung, die den Wassertank über die Pumpe mit dem Wasserinjektor verbindet, und einen Druckspeicher zum Speichern von Wasser, wobei der Druckspeicher zwischen Pumpe und Wasserinjektor angeordnet ist. The device according to the invention for injecting water for cooling of charge air located in or routed in a combustion chamber comprises a water injector, a water tank, a water pump and a piping which connects the water tank to the water injector via the pump, and a pressure accumulator for storing water , wherein the pressure accumulator is arranged between the pump and the water injector.
Damit kann gewährleistet werden, dass eine Mindestmenge an Wasser mit einem ausreichend hohen Druck eingespritzt wird. Das Einspritzen kann entweder direkt in einen Verbrennungsraum eines Verbrennungsmotors oder in einen Ansaugtrakt des Verbrennungsmotors erfolgen. Das Vorsehen eines Druckspeichers ermöglicht es, die Wasserpumpe in einem Betrieb des Verbrennungsmotors, in dem eine Kühlung der Ladeluft nicht erfolgen soll oder nur eine geringe Wassermenge zum Kühlen der Ladeluft notwendig ist, abzuschalten. Dies ermöglicht, Energie zu sparen. Des Weiteren ist sofort eine Mindestmenge an Wasser mit einem geeignet hohen Druck vorhanden, wenn Wasser zum Kühlen der Frischluft angefordert wird. Der benötigte Druck muss nicht erst durch ein Einschalten der Wasserpumpe aufgebaut werden. This can ensure that a minimum amount of water is injected at a sufficiently high pressure. The injection can be done either directly into a combustion chamber of an internal combustion engine or into an intake tract of the internal combustion engine. The provision of a pressure accumulator makes it possible for the water pump in an operation of the internal combustion engine, in which a cooling of the charge air is not to take place or only a small amount of water for cooling the charge air is necessary to turn off. This allows to save energy. Furthermore, there is immediately a minimum amount of water at a suitably high pressure when water is required to cool the fresh air. The required pressure does not have to be built up by switching on the water pump.
Der erfindungsgemäße Verbrennungsmotor umfasst eine erfindungsgemäße Vorrichtung zum Einspritzen von Wasser. The internal combustion engine according to the invention comprises a device according to the invention for injecting water.
